Cristiano Ronaldo was left covered in blood after he suffered a nasty cut to his face. Here is a video showing the gruesome injury which forced Ronaldo off at half-time, but not before he scored for the champions.

The Real Madrid man may have been wishing that the game had been called off when he required treatment in just the third minute for a nasty cut to his left eye from a wandering David Navarro elbow, but he carried on and managed to score an impressive volley, before being substituted at half-time as a precautionary measure.
